Pope Francis arrived in Cuba for a moment of great historical—and possibly geopolitical—significance. During his 3 1/2-hour visit in Havana, the pontiff is meeting with Patriarch Kirill of Moscow, marking the first time the leaders of the Catholic and Russian Orthodox Churches have been together. The event, part of a stopover on the pope’s trip to Mexico, also has other potential implications, such as drawing attention to the plight of Christian minorities in the Middle East and reflecting Russian President Vladimir Putin’s efforts to end the diplomatic and economic isolation of his country.

Global powers cautiously welcomed an agreement to work toward a pause in fighting between the warring sides in Syria and to begin delivery of urgently needed humanitarian aid, but past unsuccessful truces dampened hopes of a lasting breakthrough to end the five-year conflict. Neither President Bashar al-Assad’s regime nor its opponents had given formal approval of the agreement, which calls for a “cessation of hostilities” to start in a week. Opposition leaders and rebels said they doubted any broader cease-fire would hold, given the disagreement that still divides outside nations involved in the war and the various fighting forces on the ground over who should stop fighting whom.

Does your Valentine make you laugh? Is she easy to talk to? If so, that’s great. But if you’re looking for a long-term relationship, researchers at the U.S. Federal Reserve say a credit score may be a better measurement of compatibility. People with higher credit scores were more likely to commit to a relationship, and when they did, the relationship was more likely to last. Having similar credit scores also had a positive effect. Those with similar scores, even if they weren’t especially high, stayed together longer than those with very different scores.

Credit scores can be a sign of trust and how you deal with responsibility.

Officials at the Smithsonian’s National Air and Space Museum are creating a virtual 3-D model of Apollo 11, the spacecraft that took the first manned mission to the moon in July 1969. The virtual model will allow a closer look inside the module, the walls of which are scrawled with lunar coordinates and messages.

Edwin Aldrin—along with Neil Armstrong and Michael Collins—was one of the astronauts aboard Apollo 11.
